Elasticities Price elasticity of demand (PED) Law of demand tells us that P goes up Q goes down or P goes down and Q goes up. But it doesn’t give us any information about by how much Q changes compared to P. We want to know‚ using the PED‚ whether Q is changing by a lot compared to P‚ by a little bit compared to P or by the same rate as P. If %∆P<%∆Q‚ this good is called relatively elastic. If %∆P>%∆Q‚ this good is called relatively inelastic. If %∆P=%∆Q‚ this good is called unit elastic.

How can we recognize when we have made progress in the search for knowledge? Consider two contrasting areas of knowledge. The search for knowledge is a constantly ongoing process. So how are we to know if we have made any progress? Progress is development‚ advancement‚ and moving forward. In this case it is the progress in the search for knowledge in an area of knowing. Within the areas of knowing the strongest contradiction is between human science and natural science. Human sciences

statistics. Comparison is necessary to draw conclusions as Professor Boddington rightly points out.” the object of statistics is to enable comparison between past and present results to ascertain the reasons for changes‚ which have taken place and the effect of such changes in future. So to determine the efficiency of any measure comparison is necessary. Statistical devices like averages‚ ratios‚ coefficients etc. are used for the purpose of comparison. iv.
